Answer:
B. No
Step-by-step explanation:
In order for the relation to be a function, each X value must source exactly one arrow. The value -1 maps to two different values (2, -1), so the relation is NOT A FUNCTION.
Answer:
36
Step-by-step explanation:
24+12
For this we will use equation:
H = starting height + rate_of_growth*periods
We can mark H with index w to represent how many weeks have passed.
Because all of this we can write:
Hw = 200 + 0.5*w
To calculate height after some number of weeks all you need to do is to exchange w with number of weeks.
Answer:
There is no solution
Step-by-step explanation:
4x - 2y = 5 --> 4x - 2(2x + 10) = 5
4x - 4x - 20 = 5
4x - 4x -25 = 0
Final answer is -25 = 0 and so therefor it is no solution
A = speed of one boy
<span>a + 3 = speed of 2nd boy </span>
<span>d = speed X time ... time is 3 hrs </span>
<span>68 = 3a + 3(a + 3) </span>
<span>6a = 59 </span>
<span>a = 59/6 = 9 5/6 miles per hour </span>
<span>a + 3 = 12 5/6 miles per hou</span>
